Given numbers are 649,403,427,156

The least common multiple of numbers can be find using the prime factorization method or LCM formula.

The LCM of 649,403,427,156 is 1340166828.

Find LCM of 649,403,427,156 with Prime Factorization

Multiply the prime numbers at the bottom and the left side.

13 x 649 x 31 x 427 x 12 = 1340166828

Therefore, the lowest common multiple of 649,403,427,156 is 1340166828.

LCM formula is LCM(a1, a2, an) = (a1 x a2 x an)/{GCF(a1 x a2 x an) x common factors}

Firstly, we have to find the product of all the numbers.

649 x 403 x 427 x 156 = 17422168764

Then, let us find the GCF of these five numbers. To do so, we have to list down the factors for each number and choose the highest factor that is in all of the lists.

649 : 1, 11, 59, 649

403 : 1, 13, 31, 403

427 : 1, 7, 61, 427

156 : 1, 2, 3, 4, 6, 12, 13, 26, 39, 52, 78, 156

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 649,403,427,156, is 1.

Now, the common factors can be found like this.

649:11x 59

403:13x 31

427:7x 61

156:2x 2x 3x 13

From this, we can see that the common factors because they appear for more than two numbers. So, just multiply them all together.

13 = 13

Therefore, the value for common factors is 13.

Now that we have all the elements of the formula, we can plug them in to calculate the LCM.

LCM(a1, a2, an) = (a1 x a2 x an)/{GCF(a1 x a2 x an) x common factors}

LCM = 17422168764/(1x13)

LCM = 17422168764/13

LCM = 1340166828

Thus, we can understand that the LCM of 649,403,427,156 is 1340166828.
